Abstract
The utility model relates to an anti-falling connecting and fixing piece for a tower tray plate, which is composed of a bolt, a spacer for the bolt, a nut and a supporting frame for the nut, wherein the lower part of the supporting frame for the nut is provided with a U-shaped plate matched with the external diameter of the nut; the front and the back sides of the U-shaped plate are provided with positioning baffle plates for the nut; the upper part of the supporting frame for the nut is provided with a pair of hanging hooks which form external hanging hook shapes by the upward extension of two side plates of the U-shaped plate; the hook width of the hanging hooks is matched with the thickness of the tower tray plate. The utility model is characterized in that the utility model is also provided with the supporting frame for the nut, the fastening piece is tightened and not tightened, and the supporting frame for the nut is firmly fixed on the tower tray plate; the tower tray plate vibrates in any mode, the supporting frame for the nut is difficult to loose, and the nut is positioned in the supporting frame; the supporting frame does not fall off, and the nut is difficult to loose, thereby, the utility model solves the problem that the fastening piece falls off.
Description
Technical field
The utility model relates to the securing member that a kind of tray deck connects usefulness, and it is applicable to that the tray deck of various treating columns in oil, chemical industry and the medicine and other fields is connected.
Background technology
In prior art, common tray deck syndeton such as Chinese patent ZL00205868.5 are shown in Figure 1, and securing member wherein is made up of a screw rod, top nut pad, lower nut pad and upper and lower nut.When connecting tray deck, the people stands in the tray deck top-operation, when tightening firmware, general earlier lower nut pad and lower nut are welded on below the tray deck, then, on tray deck, screw rod are screwed in the lower nut, again the top nut pad is enclosed within on the screw rod, top nut is enclosed within on the screw rod screws at last.Wherein the welding of lower nut pad and lower nut can also be played the effect that prevents that securing member from coming off.Because tray deck is subjected to the impact of gas in the tower, the upper and lower convection type of liquid two-phase, its vibration is very big, and very easily the solder joint with lower nut shakes out, and causes lower nut to become flexible and comes off, thereby lose fastening effect.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of tray deck of slip-off preventing to connect securing member.
For achieving the above object, solution of the present utility model is as follows:
It is made up of a bolt, bolt pad, nut and nut bracket, described nut bracket bottom is a U-shaped plate that matches with the nut external diameter, and be provided with the positioning baffle of nut in the both sides, front and back of U-shaped plate, the top of described nut bracket is a pair of hook, this is extended upward by the biside plate of described U-shaped plate hook and is bent into the outer hanging hook shape, and the hook of described hook is wide matches with tray deck thickness.
The profile of above-mentioned nut is advisable to adopt square or rectangular.
By above-mentioned improvement as can be seen, the utility model is provided with a nut bracket, no matter this securing member tightens and whether does not tighten, this nut bracket all is fixed on the tray deck securely, no matter how tray deck vibrates, carriage all is difficult to throw off, and nut is arranged in carriage, as long as carriage is not thrown off, nut just is difficult to become flexible, so avoided securing member to come off.
Description of drawings
Fig. 1, overall structure of the present utility model and fastening schematic diagram.
The A-A generalized section of Fig. 2, Fig. 1.
The specific embodiment
Describe structure of the present utility model and fastening operating process below with reference to the accompanying drawings in detail.
Referring to Fig. 1, it is made up of bolt 1, bolt pad 2, nut 3 and nut bracket 4, wherein nut bracket 4 bottoms are U-shaped plates that match with nut 3 external diameters, and be provided with outstanding plate in the both sides, front and back of U-shaped plate, this plate right angle is bent into described nut positioning baffle 4.1, the top of described nut bracket is a pair of hook 4.2, and this is extended upward by the biside plate of U-shaped plate hook and is bent into the outer hanging hook shape, and the hook of hook is wide matches with tray deck thickness H.Nut 3 is inserted in the U-shaped plate, and its profile preferably adopts square or rectangular, and it is matched with the U-shaped plate easily, is also circumferentially located easily.
Referring to Fig. 2, when fastening, the nut bracket 4 that needs to have nut 3 earlier is installed in down on the screw 5.1 of tray deck 5, and described screw 5.1 should adopt square hole or oblong aperture, if adopt oblong aperture, can make the length direction of installation site in the hole of nut 3 obtain adjusting.When nut bracket 4 is installed, needs its a pair of hook 4.2 is stretched into the hole from screw 5.1 bottoms, and make the both sides of the edge of hooking screw 5.1, because the U-shaped plate has elasticity, so nut bracket is hung on the screw 5.1 preferably.
Referring to Fig. 1, when connecting tray deck, the connecting portion of upper and lower tray deck 5,6 is folded to be dropped on together, and the screw on it is aimed at mutually, and then tightens firmware again.When loading firmware, bolt pad 2 and bolt 1 are contained in the screw, bolt is screwed get final product again.When bolt screwed, the top edge of hook 4.2 was clipped in wherein by upper and lower tray deck, must be tight more on the bolt, hold just tightly more, then nut bracket is connected firmly on tray deck down, like this by firm, nut 3 just can not become flexible, and therefore, this securing member can prevent effectively that nut from coming off.
Claims (2)
1, a kind of tray deck of slip-off preventing connects securing member, it is characterized in that: it is made up of a bolt (1), bolt pad (2), nut (3) and nut bracket (4), described nut bracket bottom is a U-shaped plate that matches with the nut external diameter, and be provided with the positioning baffle (4.1) of nut in the both sides, front and back of U-shaped plate, the top of described nut bracket is a pair of hook (4.2), this is extended upward by the biside plate of described U-shaped plate hook and is bent into the outer hanging hook shape, and the hook of described hook is wide matches with tray deck thickness.
2, the tray deck of slip-off preventing according to claim 1 connects securing member, and it is characterized in that: the profile of described nut (3) is a square or rectangular.
